**v1.01.341** ZZZZ341 - Validation of the dependent pressure as a function of space
===============================================================================

**Summary:**

This test validates the application of a follower pressure whose intensity is a function of the updated space variables (:math:`\mathit{XF}`, :math:`\mathit{YF}`, :math:`\mathit{ZF}`) in 2D and 3D:


* A cube, whose Poisson's ratio is zero, is initially put into uniform compression according to :math:`Y` by a subsequent pressure depending on space;


* Then a rigid rotation is applied to the cubed around one of its edges. The pressure load multiplier function is zero at this moment, so the cube is released.


* Finally, at the last moment of calculation, the follower pressure load is applied again. This loading is a function of space so that the new position of the cube means that the pressure applied is now as follows :math:`X`.

The support reaction is recorded at the level of the embedded face. The solution is analytical.

Note the particularity of the treatment of the load with the following pressure as a function of space:


* at first, the geometry is updated to take into account the change in normal


*in a second step, the intensity of the pressure is calculated**from the updated space variables** (parameters :math:`\mathit{XF}`, :math:`\mathit{YF}`, :math:`\mathit{ZF}` in DEFI_FONCTION)

This test includes three models:


* modeling A: D_ PLAN;


* B modeling: 3D;


* C modeling: D_ PLAN with symmetrization option SYME =' OUI '.
